Eccentricity Fluctuations in p-p and Elliptic Flow

We discuss under which conditions elliptic flow becomes measurable in high- multiplicity $(dN_{ch}/dy ≥ 50)$ p-p collisions, which will soon be collected at the LHC. We observe that fluctuations in the p-p interaction region can result in a sizable spacial eccentricity even for the most central p-p collisions. Under relatively mild assumptions on the nature of such fluctuations and on the eccentricity scaling of elliptic flow, we find that the resulting elliptic flow signal in high-multiplicity p-p collisions at the LHC becomes measurable with standard techniques.
